Adjusting; beams; bearings; equi-armed balances; sensitiveness, increasing; weights ; yarns and the like, testing and weighing. -Relates to a weighing - apparatus for determining and comparing the counts of different kinds of yarn. One-seventh of a recognized unit of length is weighed in a delicate balance. In the case of cotton and spun silk, this unit of length is 840 yards ; for worsted yarn, 560 yards ; west of England yarn, 320 yards ; woollen yarn, 256 yards ; and linen, 300 yards. The beam of the balance, Fig. A, is formed of three bars braced together, graduated and provided with riders, whereby fractions of grains may be weighed by means of the rider on the uppermost bar, pennyweights by means of the rider on the middle bar, and grains by means of the rider on the lowest bar. The beam is also provided at the ends with vertically-adjustable weights E for regulating the sensitiveness of the balance, and with means for adjusting vertically the position of the knife-edges J for supporting the pans. The invention comprises the use of 247 weights each inscribed as shown in the specimens, Fig. 5, with the counts number of a particular kind of cotton yarn, the weight of one-seventh of a hank of this yarn, which is also the weight of the piece of metal forming the weight, and with the words " 1 lea," which is the name of one-seventh of a hank of cotton yarn. In addition to these " counts " weights," there are provided strips of metal &c. on which are engraved tables, specimens of which are shown in Fig. 6. The large figures are to facilitate reference only, and represent approximately the count of a particular kind of cotton yarn. The table proper is that shown in smaller letters and numerals. On the first line of each column or table is indicated a weight, and on the other lines are given the counts of yarns of the kinds known as cotton, span silk, worsted, west of England, woollen and linen respectively, of which one-seventh of a unit lenght has the weight given at the head of the table. When not in use, these bars or strips are supported in a stepped rack secured to the base-board of the balance, from which they project at each end alternately to facilitate removal and replacement ; when a bar is required for use, it is placed in the slotted blocks N, Fig. 3, carried by a frame also mounted on the base-board of the balance, and provided with a sliding pointer M to facilitate reference to any particular column or table.

Title: Improvements in or connected with Motor Cars.
Inventor: FISHER HENRY JAMES
Filed: 1901-12-06
Granted: 1902-12-04
Abstract: 24,942. Fisher, H. J. Dec. 6. Motor road vehicles.-Relates to motor cars driven by worm gearing, and comprises means for facilitating starting and stopping, and for avoiding shock. In Fig. 1, c denotes the worm-wheel on the driven shaft or axle b. The worm is mounted in bearings i, i so as to be able to move endwise against the reaction of springs j, k interposed between collars or shoulders on the worm and stationary abutments. The driving-shaft m is not able to move endwise, but engages with the worm by a sliding connection n, such as a squared portion sliding in a squared hole. At starting, the motive power either imparts a rotatory motion to the worm and immediately moves the car, or, if the load is too great to start at once, it moves the worm endwise, thus compressing one of the springs until the resultant force is sufficient to overcome the load. In like manner, if the car over-runs the motor, the springs exercise a retarding influence. The gearing may be disconnected, and the car allowed to run free, by making the abutment for the spring k movable, so that, on being rotated, the worm runs out of engagement with the wheel. In place of, or in addition to, the springs j, k, springs may be inserted between the wheel c and arms t on the shaft b, as shown in Fig. 3, the wheel c being otherwise free. Fig. 4 shows a construction of worm - wheel with antifriction rollers s. The rollers may be either spherical, as shown, or grooved, the worm being correspondingly undercut.

Granted: 1903-06-25
Abstract: 14,430. H i g - gins, F. H. W. June 25. Telegraphs. - A printing-receiver has a type-wheel shaft a provided with h a ratchetwheel b, which is driven by inclined surfaces on a forked lever k, Fig. 2, arranged so that, at high speeds, the lever attains considerable velocity before it strikes the inclined surface of a tooth of the wheel, and the blow thus delivered causes the wheel to advance rapidly until a radial face of the next tooth on it is stopped by a radial face on the lever h. Reverse motion of the shaft a is prevented by a stationary spring-pressed pawl c<1> engaging another ratchet-wheel on the shaft, this wheel having twice as many teeth as the driving- wheel b. The lever h carries an armature, and is operated by an electromagnet receiving the line currents, and a spring, or by two electromagnets. Alternating currents may be used as described in Specifications No. 25,644, A.D. 1896, and No. 6229, A.D. 1899. Spring stops x<1>, x<2> limit the movements of the lever. Printing is effected by another electromagnet k, Fig. 6, raising a platform, over which the paper strip passes, below the typewheel. The letters and other signs are carried by two type-wheels d, e on the shaft a, either of these being rendered inoperative by the interposition of a light shield f between the wheel and the paper. The shield is carried by a frame, sliding on the printing-platform in a direction parallel to the type-wheel shaft a ; the frame is so movable by a T-shaped lever 7, pivoted on the platform, that it can be raised against either of two radial pins 10, 11 on the type-wheel shaft. Synchronous movements.-A synchronizing-appliance consists of a screw-thread r, Fig. 6, on the type-wheel shaft a, moving a stop parallel to the shaft, until after a few revolutions an arm of the shaft comes in contact with the stop, preventing further rotation. The printing platform is then raised, disengaging the stop frcm the screw r, whereupon a spring returns the stop to its starting position.
